London -- Shell Chemicals says its new Caradol MD 250-10 polyol can help reduce formulation costs, enhance foam stability, and improve safety at foam production units.
The new material broadens Shell's Caradol polyols product range and is able to enhance the polymerisation level in foam and also improve foam stability and hardness, Shell commented, in a 1 July statement.
Caradol MD 250-10 was developed to boost hardness in low-density foam applications without having to increase TDI (toluene diisocyanate) levels in the formulation.
Alternatively, it can be used to reduce TDI amounts in formulations to produce foam of the same hardness, Shell said. This TDI material reduction can help foam producers decrease formulation costs and also improve safety at their production units.
Shell noted that lower TDI levels also results in more stable foams, "easing seasonal variation in foam properties associated with changes in atmospheric humidity.'
The company said it developed Caradol MD 250-10 in response to "customer concerns about having to use very high levels of TDI in existing approaches in order to produce stable and hard foam at low density."
The new polyol also demonstrates that Shell's commitment to safety extends beyond the company to its customers and partners, the group said.
Shell is making Caradol MD 250-10 in Europe and in Asia-Pacific, and it is available in all markets through Shell's global supply and logistics network, the company said.
